Back in Part 1, we looked at how the emotions expressed by people and products communicate personality traits over time. We also learned that customers are attracted to things that have an aesthetic personality that’s similar to their own,1 but they prefer products that take on a complementary role during interaction.2
In Part 2, we’ll look at how relationships are formed when people interact with products over time, and we’ll explore how people experience the emotion of “love.” Then, we’ll examine how basic product goals like desirability, usability, and usefulness relate to the different types of love. Finally, we’ll explore the A.C.T. model, a user-friendly take on using existing frameworks for designing emotional experiences.
People attribute personalities to products and interfaces and expect those products to interact according to human social rules.3 Our emotional responses to the marketing, purchase, and use of products combine over time to create emotional experiences, which further combine to create emotional relationships.4 The quality of these accumulated interactions can mark the beginning (or end) of a “relationship” between the person and the product.
Throughout our lives, we’ve all been exposed to different types of relationships, both personally and through media. We have acquaintances, coworkers, companions, friends, lovers, wives, husbands, and every combination in between. While all these relationships are important, the people we love tend to have a special place in our hearts and minds.
But even amongst those we “love,” there are a number of different relationships. Some relationships are short, passionate flings based solely on attraction or lust. Others, though lacking in physical attraction, are deep, intimate friendships formed through ongoing interaction and conversation. Others are simple marriages of convenience with a firm commitment, but little passion or intimacy.
Although these relationships might seem to be very different, the people involved might still call the emotion they share “love.” This suggests that we’re using a single term to describe what may be several different emotions. Because of this, it can be difficult to come to a mutual understanding of what the word love really means.
Some people, for example, will emphatically say how much they love certain products. But when they say they “love” products, what do they really mean? What exactly is required to feel love for a product? Is it different from the love two people might feel for one another? Is love an appropriate emotion for relationships with products?
We can gain new insights into the formation of human-product relationships by understanding how humans form relationships with one another. Let’s take a look at the different ways people experience the emotion of love to get a better understanding of what it means to “love” a product.
How do I love thee?
Sternberg5 has described human relationships in terms of three forms of love.
Forms of Love
- Passion (Infatuated Love)
- Intimacy (Friendship)
- Commitment (Empty Love)
Passion is based on aesthetics. We’re passionately attracted to certain people because of how they look, sound, smell, feel and taste. These aesthetic cues communicate information about health, reproductive fitness, fertility, and social status to potential partners 7 8. We generally evaluate these cues automatically without conscious consideration.
If a relationship had Passion but lacked Intimacy and Commitment, it would be called Infatuated Love, or lust5. This form of love would describe the quick fling or one-night stand. According to Sternberg5, relationships based solely on Passion tend to burn out quickly. We tend to be attracted to people who are about as attractive, wealthy, and educated as ourselves (i.e. those who are similar to us).
Sternberg5 defines Intimacy as Friendship, rather than sexual intimacy. Achieving Intimacy usually requires repeated conversation and interaction over time. You don’t really get to know someone well without spending time together in a variety of situations.
When we engage in conversation with another person, we make both unconscious and conscious evaluations of them. We judge whether our styles of interaction are complementary and comfortable, or similar and conflicting. Does the other person constantly interrupt when you’re talking? Are you always butting heads over who’s in charge? Does he or she give you the amount of respect you feel you deserve?
If all you had with another person was Intimacy, you’d probably be very close friends. However, you’d likely not feel much Passion or sexual attraction. If someone has ever told you that they love you, but aren’t “in love” with you, it’s likely that they were talking about feeling Intimacy without Passion.
Commitment is a mutually agreed upon agreement. In marriage, an individual consciously enters into a public contract with another person. Even in long-term relationships outside of marriage, the majority of couples in the western world still commit to an exclusive partnership. And yet, without Passion or Intimacy, Commitment is merely an empty agreement. If the only thing you had with someone was a Commitment, without any Passion or Intimacy, you’d have what Sternberg5 calls “Empty Love.”
Depending on the context, one or more of the three forms of love can occur at different times in a relationship. In the western world, Commitment usually comes after we’ve had a chance to evaluate our levels of Passion and Intimacy. At that point, we’ve hopefully decided whether the other person’s personality is a good fit for our own. In other parts of the world this may not be the case. Arranged marriages are one example of a relationship that begins with Commitment, with the expectation of Passion and Intimacy developing later.
Design goals, types of reactions & triune brain
At this point, you may be wondering how all of this relates to designing emotional experiences that encourage relationships. To start with, we could draw some parallels between the three forms of love and the three categories of product requirements I mentioned in Part 1. Here’s a quick recap:
adapted from: (Sanders, 1992), image: (van Gorp, 2012)
Discussions of emotional design often focus almost exclusively on the aesthetics or Desirability of a product. However, much like a three-legged stool, the qualities of Usability and Usefulness still need to be there for the product to stand on its own. For software and web applications, all three legs of the stool need to be there to support repeat usage and interaction.
The most primitive part of our brain (i.e. the reptilian brain), is automatic and generates unconscious emotional responses. The part of our brain that we share with mammals and a few other vertebrates (i.e. the mammalian brain), is also largely unconscious and creates our emotional experiences. The most highly evolved part of our brains (i.e. the neomammalian brain), is conscious and is where we form complex emotional relationships. These different levels of brain function can help us understand how relationships develop through small, repeated interactions.
(Demir, 2008), diagram: (van Gorp & Adams, 2012)
Over time, simple emotional responses from the reptilian brain combine with the processing of social cues from the mammalian brain to form experiences, which combine with our thoughts and emotions from the neomammalian brain to create relationships.
Design goals, types of reactions, and forms of love
Let’s quickly examine how the different types of love relate to designing for emotion. The user is attracted to the product’s aesthetics, triggering the Desire or passion to approach. If the user finds the product Usable and easy to interact with, he or she may begin to feel greater connection or intimacy with the product. If the product then displays its Usefulness by reliably and consistently fulfilling its purpose, trust and commitment can result.
Desirability is connected to product aesthetics. Usability is connected to the quality of interaction, and usefulness is connected to how well the product functions. For complex products, this process repeats itself with each use, continuing over time to form deeper relationships.
The types of love
Just as there are different types of relationships between people, there are different types of relationships between people and products. For products where the context of use is a short relationship (as with a disposable product), focusing on a single type of love (or a single leg of the stool) may be fine. Various combinations of the three forms of love describe
s many of the common relationships we see in our lives.
Types of love
- Passion + Intimacy = Romantic Love
- Passion + Commitment = Fatuous or Illusory Love
- Intimacy + Commitment = Companionate Love
- Passion + Intimacy + Commitment = Consummate Love
Types of Love
(Sternberg, 1988), diagram: (van Gorp, 2009)
Passion (Desirable) + Intimacy (Usable) = Romantic Love
When you combine the attraction of passion with the interaction and conversation of intimacy, you get Romantic Love. In human relationships Romantic Love describes physical attraction, along with a sense of deep intimate connection, without any formal commitment.
In relationships with products, we can envision attractive, usable products and services that don’t require long-term investments. Virgin Mobile, for example, offers attractive usable phones with no contractual commitment. The target audience is young and drawn to the idea of not committing to a phone plan. Even the marketing of the page–Why “Go” Beyond Talk?–could be taken as a metaphor for moving to another stage in a relationship.
Passion (Desirable) + Commitment (Useful) = Illusory love
Combining passion and commitment without any intimacy generally makes a poor foundation for a long-term relationship. This may be why Sternberg5 calls this combination “Fatuous” or Illusory Love. One example of this type of relationship would be a “sugar daddy” style relationship, where one partner is involved purely for passion, and the other is involved purely for commitment and the financial rewards that come with it.
In the world of design, attractive but unusable products are one source of this type of Illusory Love. We may purchase a product, attracted purely by its slick marketing or pleasing visual design, only to find that although it looks good on the surface and functions acceptably, it’s difficult to operate and frustrating to use.
Intimacy (Usable) + Commitment (Useful) = Companionate Love
When we combine Intimacy and Commitment, we get a good companion, hence the label Companionate Love5. This type of human relationship would describe a couple who are not physically attracted to each other, but are friendly and committed.
When we think of Companionate Love in terms of product relationships, we can imagine more utilitarian products. They’re easy to use, reliable, and perform the task for which they were designed. However, they don’t create that spark of attraction and desire, so there’s little passion involved. An example of this type of love would be your favorite hairbrush. This brush might be the one that does such a great job of styling your hair, you don’t need any other brushes. You probably don’t think much about your hairbrush when you’re not around it. But like the loss of an old friend, you may only really appreciate it once it’s gone.
Passion + Intimacy + Commitment = Consummate Love
Occasionally, human relationships seem to encompass all three forms of love. These relationships have achieved what Sternberg5 calls “all consuming” or Consummate Love. The people involved are passionately attracted to one another, have a deep intimate friendship, and a strong abiding commitment.
In human-product relationships, if a product has achieved trust by communicating a clear and consistent personality over repeated interactions, the user may be willing to consciously Commit and engage in transactions with the product. Transactions that lead to the formation of relationships leave us practically and emotionally satisfied in the long term. For interactive products that are used repeatedly, Consummate Love is what we are seeking to elicit from our users.
Designing relationships with A.C.T.
The A.C.T. model embodies the different forms of love, and can help you envision product development as a process of building relationships with users. The terms in the acronym A.C.T. were chosen to help designers understand the requirements they need to fulfill at each stage: Attract, Converse, Transact.
A.C.T. explores the relationship between Sternberg’s levels of love (passion, intimacy, and commitment) and product requirements to produce a model that is both more prescriptive for designers and more communicative for business stakeholders.
(van Gorp, 2009)
Let’s quickly summarize the perspectives embodied in the A.C.T.
- Desirability (do users find the aesthetics appealing?)
- Aesthetic properties of the product (i.e. look, sound, smell, touch, and taste)
- Unconscious, automatic responses
- Reptilian brain
- Usability (i.e. ease of use)
- How the product interacts with the user
- Unconscious and conscious experiences
- Mammalian brain
- Whether the product fulfills its function
- Conscious relationships
- Neomammalian (human) brain
A.C.T. Model Comparison
adapted from: (Sanders, 1992)(Sternberg, 1988)(Demir, 2008)(McLean, 1990), diagram: (van Gorp & Adams, 2012)
We judge products by the personalities we sense through their aesthetics and style of interaction. It takes the skill and sensitivity of designers, marketers and user experience professionals to properly identify the personality that appeals to their target audience, and then consistently design, market, advertise and package that product with the appropriate personality in mind. The A.C.T. Model can help practitioners to more fully and systematically address the requirements that lead to successful products.
To explore this idea in depth, Edie Adams and I have written a book on creating better relationships between people and products. If you’re interested in learning more about emotional design, designing personality and the A.C.T. Model, pick up a copy of Design for Emotion. The book includes over 130 images and examples, interviews with industry experts, and case studies to help you do a better job of designing for emotion, personality and relationship.
